As a side effect, Apple has also started rejecting pay-per-install apps ("freemium" apps that request the user to install companion apps to earn in-game currency). These apps were often used to game the charts by artifically inflating the download count and raising the ranking of the app in the App Store. No word on how companies like TapJoy (one of the largest "culprits") will react."
